YC Rejected? Don't give up.

Learning from mistake.

Our idea was to allow mobile data sync and we had prototype ready. We submitted our application during one of the YC round ( Last year ) and got rejected. We don't have other sources to get funding so, we stopped working on that idea. We stopped because our idea needed funding to go to next stage ( For testing multiple phones etc. )

Recently ZYB got sold for @49M.

Well! We also got rejected for other idea ( healthcare related) in last round and we are still working on it and planning to apply again for next round :).

Don't give up!. Print YC adv. and keep it near your desk to remind you your end goal.

Well that could be it. But still i think - if idea is adding more value to current industry then there is a scope. But I am not PG ( not yet ;) ) so, my thinking doesn't count ( counts for me - not for others ).

pg has stated a preference for avoiding industries wherein one has to get permission from huge companies to even exist...but then again, Loopt is perhaps his favorite YC company, and it exists only by the blessing of cell carriers. (Though one could build an iPhone/Android Loopt today without anyone's permission, but I reckon you'd have tough competition, since I'm sure Loopt will be in that space as well.)

If you've got the entrepreneurial itch, even an army of Paul Grahams shouting "NO" at you won't stop you from trying again :-) (though it might provide an interesting basis for a startup idea... imagine you had an army of PG's with their attention focused on you - can you make something out of that?)

If your idea needed funding, why did you apply to YC? You could easily get the same kind of money (if not a lot more) by visiting your local bank, talking to friends/family or simply taking out a few credit cards.

I funded my beta completely out of pocket and would only consider YC for the connections/PR and immersion into the startup world.
